Application filed April 9, 1914. Serial in. 836,655.

more s ecificall to that class thereof de- P y signed for use where apipe is not readily accessible or where no end is presented over whichthe cutter may be passed in order to position the same about the pipe.

The object or my invention is the production of a pipe cutteras-mentioned which will be of durable and economical construction andeliicient in use.

Other objects will appear hereinafter.

lVith these objects in View my invention consists in the combinationsand arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which Figure 1 isa side elevation of a pipe cutter embodying my invention, Fig. 2 is a.top plan view thereof, Fig. 3 is asection taken on line of Fig. 2, Figs.4 "and 5 are enlarged detail sections taken on substantial'ly lines g yand .2@ respectively of Fig. 1, and Fig. 6 is a perspective view of oneof the carriers of the cutter detached.-

The preferred form of construction as illustrated in the drawingcomprises an annular body adapted, when the device is in use, to bearranged about the pipe which it is desired to operate upon. Said bodyconsists of a main or relatively stationary section 1 and a secondary orrelatively movable section 1, said sections being arranged in alinementor end to end in order to constitute a COIltlIlllOllS flIlIlHlllS. Oneend of the section 1 is pivotally'connected at 3 to the correspondingend of section 1 in order to permit of the opposite end of said section1' being swung outwardly as clearly shown in dotted lines in Fig. 1 soas to permit of the device being attached to or removed from a I pipeWithout the necessity of sliding the same to position over an end of thepipe.

, The contiguous ends of the sections 1 and 1 said latch willautomatically are interlocked, that is the respective ends of thesection 1 are provided with tongues -1 and 5 which snugly engage withslots 6 and 7 respectiyely, provided in the contiguous ends of section1, such arrangement locking the sections 1 and 1 together against anyrelative lateral movement. 7 I i The free end of the section 1 isprovided with a latch 8 which is slidably mounted in a socket 9 providedin said section, being locked therein by a nut 10. The inner bev cledend of the latch S is adapted, when the section 2' is in operativerelation with the.

section 1, to engage a recess 11 provided in the adjacent side of saidsection 1 in order to releasably lock said sections together, a helicalcompression spring 12 interposed between a collar 13 formed at the innerend of said latch and the nut 10 serving to yieldingly hold said latchin operative position. The outer end of said latch is provided with aneXter-iorily projecting head as shown whereby the same may be retractedor pulled outwardly in order to disengage the slot 11 and permit or".outward swinging of the section 1. By beveling the. inner end of saidlat-ch as shown, upon rocking of said section 1 to closed position, moveout-' \vardly when the same engages with the adjacent portion of thesection 1, being moved into cngacicment with the recess 1.1 by thespring 12 when the section 1" reaches its operative position. Thus withthis arrangement upon rocking ofthe section 1' to closed position, thesame will be automatically locked in this position.

Formed in the body 11' are equally spaced radially extending socketsv14: opening at the inner side of said body as clearly 5 shown in Fig. 3.Snugly fitting said sockets for movement therein rad ally of said bodyare carriers 15. Adjustment of said carriers in said sockets isefi'ected by means of screws 16 which are rotatably mounted 1n the body1-1 but locked against longitudinal movement therein by means of nuts1'? which en- (ill 'justed inwardly or for on carriers a uiiorablinoui'rt ii: cur.-

of said on i of the device, g3, eleniei 1' s ol sold cuu :Z-l which arethreaded in the outer end of" sockets 20. Also mounted in each of thecar ii 15 is a mile. which is positioned in a socket so formed at theinner side of each carrier. laid rollers are so positioned that theinner sides thereof project beyond the inner surfaces of said carriersand said rollers are arranged in transverse alinenient with the cuttingelements for contact with the pipe or other object about which thedevice is arranged as will be readily under- "no( .l'hrough adjustuuultof the screws .e carriers 15 may be moved radiallr elf e body of the cuer in. order to lllCW. out 1;; elements ill and rollers toward so as toacconnuodate pipes of various sizes, one of said carriers being shown indotted linesin Fig. 3

ageinent with e pipe of smaller size. l fith this arrangement, upon thedevice being arranged about a pipe, the screws 16 will be adjusted inorder to more the rollers and cutting cle-' nien'ts into engagement withthe pipe :is will be readily understood. Erich-cling the bQQY l----l isan annular member .27 in which is mounted a spring pressed pawl 28adapted for engagement with ratchet teeth 2-9 which are formed in theperiphery of said body. The arrangement is such, as will be observed,

I that intermittent rotation of the body 1-l.

in order to oll'ect cutting oi? the pipe by the cutting elements of thedevice is secured by oscillution oi the member 72;. Such oscilim tion ofsaid member 27 is secured by means of an outwardly [fiOjGCtlllg handle30 which engages with a soehet 3]. formed at one side of said member"27. The member 21'' is relcasably locl-uzd in position upon the bodyl--1. by u'ieans oi pins which are remow ably threaded in said bo y,projecting therefrom for cugugjcmcnt an, inst one side of the member 27,the latter lacing held between said pins and shoulders 33 clearly shownin Fig. 2. With this arrangement it will be seen that, upon removal ofthe pins 32, the
